Dear Power BI gurus, I am stuck on this calculation, any help will be greatly appreciated.

@airportGR , The information you have provided is not making the problem clear to me. Can you please explain with an example.

Can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data.

Check if these can help

refer 4 ways (related, relatedtable, lookupvalue, sumx/minx/maxx with filter) to copy data from one table to another
